Not, of course, that the way these cards are architected makes these numbers directly comparable. When it comes to core clock speeds, little differentiates the two – the GTX 970 is only 50MHz quicker than the R9 390. That card has only 4GB of memory and its 256-bit memory interface is half the width of AMD’s new hardware. It contains 6.2 billion transistors, and the core still features 2,560 stream processors – only 256 behind the R9 390X.Īll this amounts to a convincing slate of specifications when lined up against Nvidia’s GTX 970. The old card’s core clock of 947MHz has been improved to 1,000MHz, which is only 50MHz behind the pricier R9 390X.Įlsewhere, the card remains the same. This brings a rise in clock speed from 5,000MHz to 6,000MHz, making this one of the mightiest memory configurations seen in any card available right now. The biggest change comes in the memory department, where the 4GB used on the older card has been doubled to a monster 8GB. Not surprisingly, the R9 390 shares the same architecture as the Hawaii XT core inside the R9 390X, albeit with a couple of tweaks. More specifically, the core inside this new card is dubbed Grenada Pro, and it’s based on the Hawaii Pro chip that featured in 2013’s R9 290. The R9 390 makes use of the Graphics Core Next architecture that’s been present in AMD graphics cards since 2011.

It’s business as usual for AMD, which has recycled an older part to build this new card. The current range of AMD cards seems like it’s been designed to directly compete with Nvidia products, and the new Radeon R9 390 is no exception: this £276 chip goes head-to-head with Nvidia’s GeForce GTX 970.
